Disable auto indent globally in Emacs

How to disable auto indent in Emacs globally or only for some modes?

I have a number of packages installed for RubyOnRails (ruby, html, js, css).

Let's say I want to disable autoindent for css-mode.

In my case (TypeScript + React through web-mode) the variable causing indent on RET was web-mode-enable-auto-indentation - had to toggle it from t to nil.

I guess, in general you may probably want to check all variables with indent in their names that are t. Or rather start looking from RET binding as others suggest.

For me, on emacs 24.x, M-xelectric-indent-mode toggled the behavior that I wanted to disable.

FWIW, the behavior was that RET was bound to the command newline which is defined in simple.el... Among other things, the behavior of that command is altered by electric-indent-mode.

You may want to look for variable names containing the word electric. (This is the common Emacs parlance for actions which occur automatically when particular visible characters are typed.)

In this instance, M-x apropos-variable RET electric RET shows me that there is a css-electric-keys variable containing a list of "Self inserting keys which should trigger re-indentation."

You could use M-x customize-variable RET css-electric-keys RET to set this list to nil, or add (setq css-electric-keys nil) to your init file.

Sometimes a minor mode is used to implement electric behaviours, so that you can switch them on and off more easily. Those would likely be found via M-x apropos-command RET electric RET, and you would probably use a major mode hook to ensure that the electric minor mode was disabled, in a similar fashion to this:

(add-hook 'MAJORMODE-mode-hook 'my-MAJORMODE-mode-hook)
(defun my-MAJORMODE-mode-hook ()
  (ELECTRICMODE-mode 0))
